Frequently asked questions

  • I am looking for a domain name registrant. Where can I look it up?

    The Whois is an easy-to-use tool for checking the availability of a .nl domain name. If the domain name is already taken, you can see who has registered it.

    On the page looking up a domain name you will find more information about what a domain name is, how the Whois works and how the privacy of personal data is protected. Alternatively, you can go straight to look for a domain name via the Whois.

  • I would like to transfer my domain name to another registrar. What is the procedure?

    To get your domain name transferred, you need the token (unique ID number) for your domain name. Your existing registrar has the token and is obliged to give it to you within five days, if you ask for it. The procedure for changing your registrar is described on the page transferring your domain name.

  • The details registered about me/my company are incorrect or out of date. How can I get them updated?

    To update the contact details associated with your domain name, you need to contact your registrar. Read more about updating contact details.

  • Why is my domain name in quarantine?

    When a domain name is cancelled, we aren't told the reason, so we can't tell you. You'll need to ask your registrar. The advantage of quarantine is that, if a name's cancelled by mistake, you can always get it back.

    One common reason is that the contract between you and your registrar says you've got to renew the registration every year. If you haven't set up automatic renewal and you don't renew manually, the registration will expire.

  • Ik heb een klacht over mijn provider/registrar. Kan ik daarvoor bij SIDN terecht?

    Wanneer je een klacht hebt over of een geschil met je registrar dan zijn er verschillende mogelijkheden om tot een oplossing te komen. Hierover lees je meer op pagina klacht over registrar. SIDN heeft geen formele klachtenprocedure voor het behandelen van een klacht over jouw registrar.

  • What conditions do I have to meet as a registrar?

    Would you like to be able to register domain names for customers or for your own organisation by dealing directly with SIDN? If so, you can become a .nl registrar. Read more about the conditions and how to apply for registrar status on the page becoming a registrar.

Migration to the public cloud: communications overview

An overview of our own communications and publications about our migration plans, and of certain relevant government publications.

Cloud computing concept
  • Wednesday 21 May 2025

In January 2024, we published an article on this website setting out our plan to migrate a portion of our technical infrastructure to the public cloud platform operated by Amazon Web Services (AWS). The announcement caused considerable commotion, disquiet and justifiable debate regarding the Netherlands’ digital autonomy. Since then, a great deal has been said and written about our plans, even including parliamentary questions, statements and motions. That ultimately led to constructive dialogue and further investigations. As a result, not only have our plans been refined and improved, but an important public debate has been started, about assuring the sovereignty of the Dutch digital infrastructure more generally.

We have therefore compiled an overview of our own communications and publications about our migration plans, and of certain relevant government publications. If you've got any questions about the matters covered by any of the publications, or you’d like anything added to the list, please mail communicatie@sidn.nl.
